Abstract
Description
Technical Field
[0001] This application relates to the technical field of chemical manufacturing, and more particularly, to a stirring tank for chemicals. Background Art
[0002] In the prior art, the bottom - inserted pipe of a stirring tank usually uses a soft polytetrafluoroethylene perfluoroalkoxy resin copolymer pipe (abbreviated as PFA pipe). Due to its soft texture, this type of bottom - inserted pipe can usually be directly matched and connected with the fixed joint on the tank body. However, in the technical field of chemical manufacturing, in order to meet the process requirements, hard bottom - inserted pipes are usually required. Due to their hard texture and the usually inconsistent diameters of the pipes and the fixed joints, it is difficult to match and connect with the fixed joints, making it a major problem in the current chemical manufacturing process to set hard bottom - inserted pipes in the stirring tank. Summary of the Utility Model
[0003] The purpose of this application is to provide a stirring tank for chemicals, which can effectively solve the problem of setting hard bottom - inserted pipes in the stirring tank.
[0004] The embodiments of this application are implemented as follows:
[0005] The embodiments of this application provide a stirring tank for chemicals, including a tank body and a bottom - inserted pipe; at least one fixed joint is installed on the top cover of the tank body, and each fixed joint includes an outer joint located outside the tank and an inner joint located inside the tank, and the outer joint and the inner joint are connected; the bottom - inserted pipe is located inside the tank, and the bottom - inserted pipe includes an adapter and a hard plastic pipe body. One end of the adapter is detachably connected to the inner joint, and the other end of the adapter is heat - welded to one end of the pipe body to connect the inner joint and the pipe body, and the other end of the pipe body extends towards the bottom of the tank.
[0006] In the above - mentioned technical solution, the bottom - inserted pipe includes an adapter and a hard plastic pipe body. Among them, one end of the adapter is detachably connected to the inner joint, and the other end of the adapter is heat - welded to the pipe body. By additionally providing an adapter, the connection between the hard plastic pipe body and the adapter can be realized, so as to achieve the purpose of setting a hard bottom - inserted pipe in the stirring tank to meet the production needs of chemicals; in addition, since the adapter and the inner joint body are detachably connected, different - material bottom - inserted pipes can also be replaced according to actual production needs to improve the compatibility of the equipment.
[0007] In some alternative embodiments, the material of the pipe body is polypropylene, polyvinyl chloride, polyvinylidene fluoride or polytetrafluoroethylene.
[0008] In the above - mentioned technical solution, there are many types of materials that the pipe body can use, which can provide more implementation options, thus facilitating the popularization and application of the technical solution provided by the embodiments of this application.
[0009] In some alternative embodiments, the adapter and the pipe body are made of the same material.
[0010] In the above technical solution, the adapter and the pipe body are made of the same material, which can reduce the risk of material contamination and thus obtain a product with higher purity.
[0011] In some alternative embodiments, an annular partition portion is convexly provided on the inner peripheral wall of the adapter to divide the adapter into a first adapter and a second adapter. The outer wall of the inner adapter is threadedly connected to the inner wall of the first adapter, and the pipe body is socket-welded and heat-fused to the second adapter.
[0012] In the above technical solution, the adapter is provided with an annular partition portion to divide the adapter into a first adapter and a second adapter, and they are respectively connected to the inner adapter and the pipe body according to specific connection methods. Among them, the first adapter is threadedly connected to the inner adapter, and the second adapter and the pipe body are socket-welded and heat-fused. This setting form has the advantages of being convenient for assembly and having a relatively stable overall structure after assembly.
[0013] In some alternative embodiments, the inner diameter of the annular partition portion is the same as the inner diameter of the pipe body.
[0014] In the above technical solution, the annular partition portion and the pipe body are set to have the same inner diameter so that they can have a smooth transition at the connection, which can effectively solve the problem that materials are likely to deposit here, thereby reducing the risk of the pipeline being blocked by materials.
[0015] In some alternative embodiments, the mixing tank further includes a fixing member. One end of the fixing member is connected to the inner wall of the top cover, and the other end is clamped to the outer peripheral wall of the pipe body.
[0016] In the above technical solution, the mixing tank is provided with a fixing member that can be clamped to the outer peripheral wall of the pipe body, which can improve the connection stability between the bottom inserting pipe and the inner adapter.

This specific form of fixing member can have a large space between the adapter and the connecting section of the fixing member after installation, which is convenient for subsequent disassembly and assembly of the adapter.
[0019] In some alternative embodiments, the central angle of the clamping groove is 180°.
[0020] In the above technical solution, the central angle of the clamping groove on the fixed section is limited to 180° (i.e., just clamping half of the pipe body), so that there is a large enough contact area between the inner wall of the clamping groove and the outer peripheral wall of the pipe body, thereby improving the fixing stability of the fixing member to the pipe body.
[0021] In some alternative embodiments, a reinforcing member is provided on the inner wall of the tank body, and the reinforcing member extends along the circumferential direction of the tank body and is connected end to end.
[0022] In the above technical solution, adding a reinforcing member extending along the circumferential direction of the tank body on the inner wall of the tank body can improve the structural strength of the tank body, thereby extending its service life. At the same time, it can also improve the stability of the equipment during operation.
[0023] In some alternative embodiments, a plurality of reinforcing members are provided, and the plurality of reinforcing members are spaced apart along the height direction of the tank body.
[0024] In the above technical solution, providing a plurality of reinforcing members and spacing them apart along the height direction of the tank body can further improve the structural strength of the tank body. BRIEF DESCRIPTION OF THE DRAWINGS

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.
[0037] The following specifically describes a stirring tank for chemicals of the present application.
[0038] Refer to Figure 1 and Figure 2 As shown in [Figures 1 and 2], the embodiment of the present application provides a stirring tank 10 for chemicals, including a tank body 100 and an inserted-bottom pipe 200; at least one fixed joint 111 is installed on the top cover 110 of the tank body 100, and each fixed joint 111 includes an outer joint 111a located outside the tank body 100 and an inner joint 111b located inside the tank body 100, and the outer joint 111a and the inner joint 111b are in communication; the inserted-bottom pipe 200 is located inside the tank body 100, and the inserted-bottom pipe 200 includes a swivel joint 210 and a rigid plastic pipe body 220. One end of the swivel joint 210 is detachably connected to the inner joint 111b, and the other end of the swivel joint 210 is heat-welded to one end of the pipe body 220 to communicate the inner joint 111b and the pipe body 220, and the other end of the pipe body 220 extends towards the bottom of the tank body 100.
[0039] In the present application, the inserted-bottom pipe 200 includes a swivel joint 210 and a rigid plastic pipe body 220. Among them, one end of the swivel joint 210 is detachably connected to the inner joint 111b, and the other end of the swivel joint 210 is heat-welded to the pipe body 220. By additionally providing the swivel joint 210, the communication between the rigid plastic pipe body 220 and the swivel joint 210 can be realized, so as to achieve the purpose of setting the rigid inserted-bottom pipe 200 in the stirring tank to meet the production needs of chemicals; in addition, since the swivel joint 210 and the inner joint 111b are detachably connected, different materials of the inserted-bottom pipe 200 can also be replaced according to actual production needs to improve the compatibility of the equipment.
[0040] It should be noted that in the embodiment of the present application, by adding a swivel joint 210 to connect the pipe body 220 and the fixed joint 111, compared with directly docking the pipe body 220 with the fixed joint 111 (such as threaded connection), the damage to the pipe body 220 can be reduced (threads need to be provided on the pipe body 220, which will cause damage to the pipe body), and its service life can be improved. At the same time, the existing size and specification of the hard pipe body 220 can be directly used without remanufacturing according to the size of the fixed joint 111, and the manufacturing cost can also be reduced.
[0041] It should be noted that the number and arrangement of the fixed joints 111 are not limited and can be adjusted according to actual needs. For example, two rows of fixed joints 111 can be set on the top cover 110 of the tank body 100, wherein one row has three spaced-apart fixed joints 111 and the other row has five spaced-apart fixed joints 111.
[0042] As an example, the material of the tube body 220 is polypropylene, polyvinyl chloride, polyvinylidene fluoride or polytetrafluoroethylene.
[0043] In this embodiment, a variety of materials can be used for the tube body 220, and a large number of feasible implementation plans can be provided, thereby facilitating the promotion and application of the technical solution provided in the embodiment of the present application.
[0044] As an example, the material of the adapter 210 is the same as the material of the tube body 220 .
[0045] In this embodiment, the adapter 210 and the tube body 220 are made of the same material, which can reduce the risk of material contamination, thereby preparing a product with higher purity.
[0046] See also Figure 2 As an example, the stirring tank further includes a fixing member 300 , one end of which is connected to the inner wall of the top cover 110 , and the other end of which is clamped to the outer peripheral wall of the tube body 220 .
[0047] In this embodiment, the mixing tank is additionally provided with a fixing part 300 which can be engaged with the outer peripheral wall of the tube body 220, which can improve the connection stability between the bottom tube 200 and the inner joint 111b. At the same time, the bottom tube 200 can also be limited in the horizontal direction, thereby reducing the shaking amplitude during the material mixing process, thereby improving the operating stability of the equipment.
[0048] It should be noted that the specific form of the fixing member 300 is not limited and can be adjusted according to actual needs as long as it can be clamped and fixed to the pipe body 220 .
[0049] See also Figure 2 As an example, the fixing member 300 is L-shaped, and the fixing member 300 includes a connecting section 310 and a fixing section 320. The connecting section 310 is connected to the inner wall of the top cover 110, and the fixing section 320 is provided with a snap-in groove 321 corresponding to the outer peripheral wall of the tube body 220 at one end away from the connecting section 310.
[0050] In this embodiment, the fixing member 300 is provided as an L-shaped fixing member 300 composed of a connecting section 310 and a fixing section 320. Among them, the connecting section 310 is connected to the inner wall of the top cover 110, and the fixing section 320 is clamped to the outer peripheral wall of the pipe body 220. After being installed, this specific form of the fixing member 300 can create a relatively large space between the adapter 210 and the connecting section 310 of the fixing member 300, facilitating the subsequent disassembly and assembly of the adapter 210.
[0051] It should be noted that the central angle size of the clamping groove 321 (i.e., the size of the clamping groove 321) is not limited and can be adjusted according to actual needs. For example, it can be any point value among 160°, 170°, and 180° or the range value between any two of them.
[0052] As an example, the central angle of the clamping groove 321 is 180°.
[0053] In this embodiment, the central angle of the clamping groove 321 on the fixing section 320 is limited to 180° (i.e., just clamping half of the pipe body 220), so that there is a large enough contact area between the inner wall of the clamping groove 321 and the outer peripheral wall of the pipe body 220, thereby improving the fixing stability of the fixing member 300 to the pipe body 220.
[0054] Refer to Figure 3 , as an example, an annular partition 211 protrudes from the inner peripheral wall of the adapter 210 to divide the adapter 210 into a first joint 212 and a second joint 213. The outer wall of the inner joint 111b is threadedly connected to the inner wall of the first joint 212, and the pipe body 220 is inserted and heat-welded to the second joint 213.
[0055] In this embodiment, the adapter 210 is provided with an annular partition 211 to divide the adapter 210 into a first joint 212 and a second joint 213, and they are respectively connected to the inner joint 111b and the pipe body 220 in a specific connection manner. Among them, the first joint 212 is threadedly connected to the inner joint 111b, and the second joint 213 and the pipe body 220 are inserted and heat-welded. This setting form has the advantages of being convenient for assembly and having a relatively stable overall structure after assembly.
[0056] It should be noted that the standard for the annular partition 211 to divide the adapter 210 is not limited and can be adjusted according to actual needs. For example, along the axial direction of the adapter 210, the adapter 210 can be evenly divided, or the size of the first joint 212 can be larger than that of the second joint 213, or the size of the first joint 212 can be smaller than that of the second joint 213.
[0057] As an example, the inner diameter of the annular partition 211 is the same as the inner diameter of the pipe body 220.
[0058] In this embodiment, the annular partition portion 211 and the pipe body 220 are arranged in a form with the same inner diameter, so that they can have a smooth transition at the connection, effectively solving the problem that materials are likely to deposit here, thereby reducing the risk of the pipeline being blocked by materials.
[0059] Refer to Figure 4 , as an example, a reinforcing member 120 is provided on the inner wall of the tank body 100, and the reinforcing member 120 extends along the circumferential direction of the tank body 100 and is connected end to end.
[0060] In this embodiment, by adding a reinforcing member 120 extending along the circumferential direction of the tank body 100 to the inner wall of the tank body 100, the structural strength of the tank body 100 can be improved, thereby extending its service life. At the same time, the stability of the equipment during operation can also be improved.
[0061] It should be noted that the specific structure of the reinforcing member 120 is not limited and can be set according to the conventional selection in the art. For example, it can be an arc-shaped strip protruding from the inner wall of the tank body 100.
[0062] As an example, a plurality of reinforcing members 120 are provided, and the plurality of reinforcing members 120 are spaced apart along the height direction of the tank body 100.
[0063] In this embodiment, by providing a plurality of reinforcing members 120 and spacing them apart along the height direction of the tank body 100, the structural strength of the tank body 100 can be further improved.
[0064] It should be noted that neither the specific number of the reinforcing members 120 nor the distance between adjacent reinforcing members 120 is limited and can be set according to the conventional selection in the art.
[0065] It should be noted that for the structural or functional units in the chemical mixing tank 10 that are not specifically described or limited, they can be set according to the conventional selection in the art.
[0066] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
